  Zwitterionic oligonucleotides with 2′-O-[3-(N,N-dimethylamino)propyl]-RNA modification: synthesis and properties

  摘要：

  A novel 2'-modification, 2'-O-[3-(N,N-dimethylamino)propyl] or 2'-O-DMAP, has been incorporated into oligonucleotides and compared to the known 2'-O-(3-aminopropyl) or 2'-O-AP modification for antisense properties. The 2'-O-DMAP modified oligonucleotides exhibit very high nuclease resistance like the 2'-O-AP modification due to the 'charge effect' and maintain high binding affinity to target RNA relative to known modifications when a few 2'-O-DMAP residues are dispersed throughout the oligonucleotide.

• An efficient method for the synthesis of 2′-O-modified nucleosides via double alkylation using cyclic sulfates

  日期：2000.3

  The alkylation of N-3-benzyloxymethyl-5-methyluridine with 1,3,2-dioxathiolane 2,2-dioxide or 1,3,2-dioxathiane 2,2-dioxide resulted in a 2'-O versus 3'-O selectivity of 3:1, respectively. The resulting product has a built-in sulfate leaving group at the terminal end of an ethyl or propyl carbon chain, which can be displaced with sulfur and nitrogen nucleophiles to produce modifications at the 2'-O or 3'-O positions.
